Bicycle: Whole or Just Parts (Coquitlam Maillardville)

Hello everyone,

I have been watching a lot of YouTube videos on how I could build my own bicycle, with spare parts

Now, I, myself already have a bicycle, ALL THE WAY BACK FROM MY LAST YEAR OF ELEMENTARY SCHOOL (2001-2002ish?), but I haven’t ridden on it much since I tried cycling to and from middle school,

BUT, MY MOTHER, whom I wish would get more exercise, DOESN’T HAVE a bicycle, and she is a REAL PENNY PINCHER, and would probably XXX DEFINITELY WON’T SPEND two to three hundred dollars on a bicycle, just the exercise, a little more conveniently

I am not looking for someone to give me a BRAND NEW SPARKLING bicycle, but if you have an old bike, HOPEFULLY with little to no rust, or have a bicycle frame with MASHED UP wheels, or vice-a-versa,

PLEASE GIVE ME A SHOUT OUT ~!
THANKS EVERYONE ;)
